BUCKLE.

SPECIFICATION forming part of Letters Patent No. 426,678, dated April 29, 1890.

Application led January 21, 1890l Serial No. 537,600. (No model.)

T0 all whom it may concern:

Be it known that I, JONAS PARKER, a citizen of the United States, residing at Williamsport, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Buckles; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, wherein- Figure l is a front elevation of a portion of a suspender and tabs, showing a buckle embodying my invention in connection therewith. Fig. 2 is a section on the line .fr m, Fig. l. Fig. 3 is a detached view of the buckle spread open. Fig. 4is a section of the buckle on the line y y, Eig. 3. Fig. 5 is a modification of the buckle, wherein but a single bedbar and a single slot in the presser-plate are provided. Fig. 6 is a modification, in which both the frame and the presser-plate of the buckle are formed of wire. Figs. 7 and Sare views of the draft-hook, showing modified forms of spring locking-lng on the shank thereof. Figs. 9, l0, 1l, and l2 show various modifications of the projecting bed-bar.

Like symbols refer to like parts wherever they occur.

My present invention relates generally to the construction of buckles, but is more especially intended to embody certain features of construction of particular value in that class of buckles which combine a bed-bar, a presser-bar or presser-plate pivoted on the bed-bar, and a tab-ring hook or draft-hook pivoted on the presser-bar, for which Letters Patent No. 417,582 were granted to me on December 17, 1889; and it consists, first, in providing the draft-hook with a lock adapted to engage the frame and lock or hold the drafthook in position, and also hold the slotted presser-plate down on the frame and bed-bar; second, in providing the presser-plate with a lip or projection, which forms a guard, covering, or shield for the draft-hook, not only serving to prevent the escape of the tab-ring from the hook,but also the wear or fraying of the garments by the nose of the draft-hook.

There are other minor features of invention, all of which will lhereinafter more fully appearo I will now proceed to describe my invention more specifically, so that others skilled in the art to which it vappertains may apply the same.

In the drawings, A indicates a strap or the web of a suspender; B B, the usual suspendertabs or any equivalent strap; O, abuckle embodying my invention, and D a tab-ring or equivalent means of connecting the strap or straps B with the buckle.

The buckle O is composed of a frame 1, which may be of any suitable shape, and is preferably formed of wire, said frame constituting the support of one or more bed-bars 2, attached to the frame at suitable distances from the top and bottom bars of the frame l. The bed-bar 2 has a raised central portion2, which may be formed by bending the wire, if wire is used for the bed-bar, or by projecting shoulders in case a solid bed-bar is used. Any number of such bed-bars may be used, according to the Width of the buckle, though one or two will generally suffice. The raised central portion 2 of the bed-bar is of a length adapted to enter a corresponding slot in the presser-plate of the buckle. The raised central portion 2a of the bed-bar 2 may be provided on its face with ribs running at diverging angles from the center of the bed-bar, as indicated in Fig. 9; or, what is the same thing, instead of ribs, diverging grooves may be substituted, as shown in Fig. ll. Such construction of the bed-bar will tend to spread the web and cause it to choke the orifice between the shoulders of the bed-bar and the edges of the slots of the slotted presser-plate.

Figs. 10 and 12 show the square-shouldered wire and solid bed-bar hereinbefore referred to as commonly used without groove or rib, which will suffice where the web or strap is of a character not likely to slip on the bed-bar.

Pivoted on the top bar l of the frame l is a slotted presser-bar or presser-plate 3, having a slot or slots 3b, corresponding in number with the projecting bed-bars 2. In case it is desired to form the whole buckle of wire, the slots 3b may be formed by bending or folding the Wire in reverse folds, as indicated in Fig. 6 of the drawings. I prefer, however, to form the pressenbar or presser-plate 3 of ISO sheet metal, as shown in Figs. l, 2, 3, and 4, said plate-being pivoted on the top bar lL of the frame and provided at its lower edge with a downwardly-projeeting tongue 4, to form a guard or shield for the drafthook 5 indicates the draft-hook pivoted on the lower edge of the slotted presser-plate and adapted lto pass under the' bottom bar lb of the frame l. The nose of this hook niayproject either forward or back, as preferred, but is usually turned to the front, so as to rest under the shield or guard 4 when the said guard 4 is provided.

The shank of the hook 5 is bent, folded, or otherwise shaped, as at 5b, to form a spring locking-lug, which engages either with the bottom bar lb of the frame l or with an offset or swell 6, formed on said bottoni bar, as the case may be, the latter construction being preferable, as the swell 6 of the bottom bar facilitates the passing of the pivoted draft-hook behind the bottom bar of frame l.

The locking-lug 5b may be given more or less spring by forming it as an open fold or double bend, as shown in Figs. '7 and 8, and its hold on the bottom bar lb may be increased by concavin g the locking-lug 5b on its interior, as shown in Fig. 7 This locking-lug 5b on the shank of the hook 5 not only serves to secure the hook, but also serves to draw down and hold the slotted presser-plate over the bed-bar and prevent the accidental shifting of the buckle C on the web A.

The construction of the buckle being of the general character hereinbefore specified, it is applied to a strap or web as follows: The buckle is spread open, as shown in Fig. 8. The web A is then passed under the top bar l, over the bed or bed-bars 2, and under the bottom bars lb, after ,which the presser-plate 3 is brought down on the web, as shown in Figs. l and 2, the pivoted draft-hook 5 is fine the slotted presser-plate.

passed under the bottom bar `lb, so as to rest directly on the face of web A, and the locking-lug 5b is sprung under the frame or the swell 6 thereof, so as to draw down and con- The drafthook 5 will rest under the guard tongue or shield 4, which will not only prevent the escape of the tab-ring'D, but will also prevent the hook 5 from wearing or fraying the garments.

Having thus described the construct-ion and operation and advantages of my invention, what I claim, and desire to secure by Letters Patent, is

l. In a buckle, the combination, with the frame, of a bed-bar secured thereto, a presserplate pivoted on the frame of the bed-bar, and a draft-hook pivoted on the presser-plate and provided with a lug or projection on its shank to engage the bottom barof the buckleframe, substantially as and for the purposes j specified.

2. In a buckle, the combination, with the frame, of a bed-bar, a presser-plate provided with a tongue or hook shield, and a drafthook pivoted on the presser-plate beneath the shield or tongue thereof and provided with a lug or projection on its shank to engage the bottom bar of the buckle-frame, substantially as and for the purposes specified.

3. In a buckle, the combination of a frame having a raised bed-bar, aA slotted presserplate pivoted on'the frame, and a draft-hook pivoted on the presser-plate and provided with a locking-lug adapted to engage the lower bar of the frame, substantially as and for the purposes specified.

4. In a buckle, the combination of a frame having a raised bed-bar, a slotted presserplate pivoted on the frame of the bed-bar and provided with a projecting tongue or shield at its opposite edge, and a draft-hook pivoted on the presser-plate beneath the tongue or shield and provided with a locking-lug adapted to engage the bottom bar of the frame, substantially as and for the purposes specified.

5. In a buckle, the combination, with the frame, of abcd-bar, a presser-plate pivoted on the frame, and a draft-hook pivoted on the presser-plate and provided on its shank with an open-fold spring locking-lug, substanti ally as and for the purposes speciied.

6. In a buckle, the combination, with the frame, of a bed-bar, a presser-plate pivoted on the bed-bar frame, and adraft-hook pivoted on tlie presser-plate and having on its shank an open-fold spring locking-lug, the fold which forms the locking-lug being curved or concave on the interior, substantially as and for the purposes speciiied.

In testimony whereof I afX my signature, inl

presence of two witnesses, this 20th day of January, 1890.

JONAS PARKER.
